Embodiment
Below in conjunction with concrete drawings and Examples, the invention will be further described.
As shown in Figure 1: better select slip ring degree of protection to be IP23 motor for the environment of plant, in order to greatly improve slip ring cooling effect, reduce the accumulation of the carbon dust that in the past traditional axial ventilation brings to greatest extent, the present invention includes slip ring cover body and one end and stretch into rotating shaft 10 in described slip ring cover body, motor sliding ring 13 is positioned at the end that slip ring cover body is stretched in rotating shaft 10; The top of described slip ring cover body is provided with air intake web plate 1, and the side of contiguous air intake web plate 1 is provided with fan 2 in slip ring cover body, and described fan 2 is arranged in rotating shaft 10 by fan mounting panel 9, and fan 2 can be followed rotating shaft 10 and rotated in slip ring cover body; Top in slip ring cover body is provided with interior wind scooper 3, described interior wind scooper 3 is positioned at the outside of fan 2, the top of slip ring cover body forms the first air duct 14 and the second air duct 15 by interior wind scooper 3, enters by fan 2 air-flow in slip ring cover body directly to blow to motor sliding ring 13 surface by the first air duct 14, second air duct 15.
Particularly, one end of rotating shaft 10 is stretched in slip ring cover body, air intake web plate 1 is positioned at the top of rotating shaft 10, rotating shaft 10 can drive fan 2 and motor sliding ring 13 to rotate in slip ring cover body, by the rotation of fan 2, can by air intake slip ring cover body external for slip ring cover, and along with the rotation of fan 2, air-flow is moved upward, enters respectively in the first air duct 14 and the second air duct 15.Interior wind scooper 3 in the outside of fan 2, and adapts to the inner wall shape of slip ring cover body, to form the first air duct 14 and the second air duct 15 in slip ring cover body.Interior wind scooper 3 is positioned at the side of contiguous air intake web plate 1 in slip ring cover body, the width of interior wind scooper 3 is less than the upper width of slip ring cover body, to make to form the first air duct 14 between interior wind scooper 3 and slip ring cover body upper inside wall, the second air duct 15 is formed in interior wind scooper 3, air-flow directly can be blowed to the surface of motor sliding ring 13 by the first air duct 14, second air duct 15, avoid mutually blocking between motor sliding ring 13, thus enough blast can be provided thus take away carbon brush abrasion produce carbon dust.
Described slip ring cover body comprises lower cover 8, and the bottom in lower cover 8 is provided with air-out web plate 7, and described punishment web plate 7 is positioned at immediately below motor sliding ring 13.In the embodiment of the present invention, entering air flow energy in lower cover 8 after blowing over motor sliding ring 13, to discharge slip ring cover by air-out web plate 7 external, and the carbon dust that air-flow is taken away is discharged by air-out web plate 7.When carbon dust is assembled on air-out web plate 7, in order to prevent web plate from blocking, only need periodic cleaning air-out web plate 7.The top of slip ring cover body is upper outlet body 5, form the version of hemispherical dome between upper outlet body 1 and lower cover 8, the passage between the outer wall of interior wind scooper 3 and the inwall of upper outlet body 5 forms the first air duct 14, and the end angle of interior wind scooper 3 is streamlined, thus can windage be effectively reduced, improve wind speed.In addition, described slip ring cover body comprises outside jacket plates 6, and described outside jacket plates 6 and air intake web plate 1 lay respectively at the both sides of slip ring cover body.
Top in slip ring cover body is provided with horizontal baffle 11, and horizontal baffle 11 is positioned at the top of motor sliding ring 13, described horizontal baffle 11 has and can allow the partition board hole that in the first air duct 14, second air duct 15, air-flow passes through; The internal air baffle 4 being used for leading to air-flow in the second air duct 15 is set in the below of horizontal baffle 11.
Described internal air baffle 4 is perpendicular with horizontal baffle 11, arranges and the vertical clapboard 12 of internal air baffle 4 in parallel distribution in the below of horizontal baffle 11, the contiguous fan 2 of described vertical clapboard 12.
In the embodiment of the present invention, the shape of horizontal baffle 11 is consistent with the shape on slip ring cover body top, and a part for interior wind scooper 3 is positioned at the below of horizontal baffle 11, and the major part of interior wind scooper 3 is positioned at the top of horizontal baffle 11.Vertical clapboard 12 is between fan 2 and internal air baffle 4, fan 2 is between vertical clapboard 12 and air intake web plate 1, vertical clapboard 12 and internal air baffle 4 are all positioned at immediately below wind scooper 3, upper end and the horizontal baffle 11 of vertical clapboard 12 are fixed, vertical clapboard 12 forms the air inlet of the second air duct 15 with the side inwall of interior wind scooper 3, between the inwall of the inwall of internal air baffle 4 and interior wind scooper 3 opposite side, the outer wall of interior wind scooper 3 and upper outlet body 5, passage capable of being ensures that air-flow directly blows to motor sliding ring 13 surface, is conducive to the smooth discharge of wind-guiding and carbon dust.And spray the anti-arc magnetic paint of one deck at slip ring cover surface of internal cavity, make surface of internal cavity very smooth, effectively prevent carbon dust in the attachment of inner chamber.
Current Ye You producer is the cooling effect improving slip ring, adopts way slip ring cover adding cooling blower, by cooling blower to slip ring air blast.Slip ring cover makes octahedron, and two cooling blowers are contained on octahedral two sides, and the wind that blower fan produces directly blows to slip ring can improve slip ring cooling, and this kind of band forces the structure of blower fan, and not only cost is higher, also brings a new fault point.Force the power supply source of blower fan once the cooling that must affect slip ring thus have impact on the operation of whole motor of breaking down.
Aeration structure of the present invention can replace band completely and force blower fan to the wind path structure of slip ring air blast, eliminate because increasing forcing functions blower fan and a set of low-tension supply of supporting increase and related Control System, and the existence of cooling blower adds extra unreliable factor.Cooling blower hardly possibility fault-free, nothing is safeguarded, Novel slip-ring ventilating system is by providing power with the fan of motor coaxle, and have the identical life-span with motor, reliability is self-evident.
The present invention ensures the condition of motor safety and reliability when not increasing any extra manufacturing cost under, in slip ring cover body, the first air duct 14 and the second air duct 15 is formed by interior wind scooper 3, first air duct 14, air flow energy in second air duct 15 directly blows to the surface of motor sliding ring 13, air-flow and carbon dust are discharged by air-out web plate 7, the little wind speed of windage is high, good cooling results, not easily accumulation carbon dust, can greatly improve slip ring cooling effect, reduce the accumulation of the carbon dust that in the past traditional axial ventilation brings to greatest extent, greatly improve sliding ring brush frame system reliability, the good factory and enterprise of environmental condition is not only provided cost savings but also eliminate potential safety hazard when selecting motor.
Above-described is only the preferred implementation of this patent, and this patent is not limited to above embodiment.Be appreciated that the oher improvements and changes that those skilled in the art directly derive or associate under the prerequisite of the spirit and design that do not depart from this patent, all should think be included in this patent protection range within.
